The Duke can bite. Rudder force required nearing Vmca is an awful lot. Vs is about 73kts, Vmca pretty much the same (maybe a couple of kts more) and Vyse out at 107kts. I always thought the aircraft was a bit quirky and nowhere near as nice to fly as the C90. I certainly wouldn't fancy the challenge of trying to fly away if an engine let go immediately after take-off as it feels nowhere near as forgiving as a C421 or PA31 in such circumstances.
